nnwAnnJ. FORD, or sPoKAnE, wAsHINe'roN I GAUGE Application filed November 5, 1929. Serial No; 404,963,

This invention relatesto new and useful improvements in liquid levelgauges more particularly adapted for use in conjunction with coffee potsand other. vessels to deter.-

wl mine the contents thereof by cupfuls.

7 Another object of the invention contemplatesitheprovision andarrangement of a float operated gauge element.

An additional object of the invention con 10 sists of a slide connectionbetween the float Viththe above and other objects in view,

theiinvention further consists of the followingnovel features anddetails of construc- -20 tion, to be hereinafter more fully described,

illustrated in the accompanying drawing and pointed out in the appendedclaims.

In the drawing:

Figure 1 is a vertical sectional view taken 5 througha percolator withthe invention applied.

Figure 2 is a horizontal sectional view taken on line 22 of Figure 1.

Figure 3 is a horizontal sectional view taken on line 83 of Figure 1.

Figure 1 is a sectional view taken on line H of Figure 1.

Referring to the drawing in detail wherein like characters of referencedenote corresponding parts, the reference character 10 indicates thehousing or body portion of the coffee pot or peroolator including areduced neck portion telescopically associated withv the dependingflange portion 12 of a closure lid 13 therefor. A transparentdome,,indicated as at 14, having a knob or finger engaging portion 15upon the upper portion thereof receives an upstanding annulus 16 uponthe closure lid or top 13 in the manner suggested in Figure 1. Theforegoing construction is conventional and forms no part of the presentapplication for Letters-Patent but is merely mentioned for purposes ofillustration in bringing forward the novel ad- 0 vantages of the caseinstant. I

In. carrying out the invention I provide a housing member 17 of tubularformation having wide and narrow oppositely disposed lon-, gitudinallyextending grooves 18 and 19 respeotively upon the inner side wallthereof. A float member 20 of hollow formation carries outwardly,laterally and oppositely projectin'g studs21 upon the outer side wallthereof and which are dimensionally proportionate to therespectivewidths of the grooves 18 and 19 for sliding action therein. In orderthat the utmost proficiency of operation may be derived from the novelgauge equipped cofi'ee potor percolator the respective studs are worn intheir respective grooves and by arranging one of the studs larger thanthe other it-will be impossible to assemble the gauge in a wrongfulmanner. The tubular housing member 17 is supported atits lowermost endand extends asa continuation upon the upper portion of a frustoconicalshaped base member 22 for'aminated in the manner suggested in Figures 1and 4 of .the drawing whereby the contents of the coffee pot orpercolator willalso seek its .level"within the tubular housing member.

The base member 22 is preferably centrally disposed upon the bottom wallof the percolator or coffee pot and to facilitate precision as .tocenteringiat all times, it is necessary .to project or otherwise disposean ear 23 carried upon the bottom wall of the percolator or cofiee potwithin a slot orcut-out por tion 2 1 in the periphery of the base member22.

The gauge element, referred toin the fore going, is in the nature of astandard 25 having a pointed lowermost extremity mounted for rotaryoscillatory movement within a pocket or socket opening 27 in a fixedbearing member 28 disposed upon the upper surface of the bottom wall forthe percolator or coffee pot and within the confines of the base member22. As shown, the standard or gauge element is provided with multiplelongitudinally disposed spiral. grooves 29 which receive trunnions .30inwardly pro= jecting from diametrically opposite sides of the innerside wall of, the float.

From the foregoing description and accomsit projecting pointedprojections 32 engagcable with the adjacent surface portions 0 l taestandard 25 to prevent tilting of the 1 whereby binding action betweenthe h-at and standard will not occur.

A gauge element in the nature of an enlargeinent head 33 carried uponthe uppermost end of the standard 25 and numerically calibrated atspaced intervals tangentially thereof is designed to indicate thecontents of the percolator or coltce pot by cupluls lhese calbrationsmay register with the handle or spout oi the percolator or colleepotreservoir or body.

A form of receptacle, indicated as at 34: and of conventional form, isprovided with a toraminaten or reticulated bottom through which theessence of the coiiee grounds may drain into the body of the receptacledue to the percolating action 01 the boiling watei boiling over theuppermost end of the tubular housing member 1?. The receptacle 34 isseated upon the upper surface of an annu lar flanged support 35encircling the outer portion of the tubular housing member 17 in themanner suggested in Figure 1 of the drawing.

The invention is susceptible of various changes in its form, proportionsand minor details of construction, and the right is herein reserved tomake such changes as properly fall within the scope of the appendedclaims.

Having described the invention, What is claimed is 1-- 1. A liquid levelgauge for use within reservoirs and the like comprising a tubularhousing member having a foramina-ted base member, a float disposed andmounted for reciprocating action within said housing, a gauge elementextending centrally and longitudinally through the housing, pin and slotconnections between the float, housing and gauge element respectively toimpart rotary oscillatory novement to the gauge element, and anenlargement carried upon the upper most visible portion of the gaugeelement calibrated at spaced intervals tangentially thereof to indicatethe contents of the reservoir by known quantities.

2. A liquid level gauge for use within reservoirs and the likecomprising atubular housing member having afrusto-conical shapedtoraminated base member adapted to seat upon the upper surface andbottom wall of a. receptacle, a float disposed and mounted forreciprocating action within said housing, a gauge element extendingcentrally and longitudinally through the housing, pin and slotconnections between the float, housing and gauge element respectively tofacilitate the imparting of rotary oscillatory movement to the gaugeelement, an enlargement carried upon the uppermost visible portion ofthe gauge element being calibrated at spaced intervals tangentiallythereof to indicate the contents of the reservoir by known quantities,and a bearing seat included within the bottom of the reservoir for thelowermost depending end of the gauge element.
